PATENT OFFICE. l

GAS-ENGINE.

To all lwhom t may concern Be it known thatI, CHARLES P. 'SKUBLIN, acitizen of Russia, residing 'at Detroit, county ofWayne, CState ofyMichifan, have invented a 'certainnew and useful ymprovenient inGasdngines, and declare'thefollowingto be a full, clear, and exactdescription of the saine, such as will enable others skilled inthe artto Ywhich it pertains to make and luse the same', reference being had tothe accompanying drawings, which form 'A Va partV of this specification.

VMy invention relates to an improvement `in internal combustion engines,shown in theV accompanying drawings and more particularly pointed out inthe following specification and claims.

This invention is designed as animprovel ment on that' shown anddescribed in United States Letters Patent No. 1250683, issued to meDecember 17, 1917. s

One ofthe objects of the present invention is to provide a single rotaryvalve adapted to control both the inlet and exhaust ports of the severalcylinders of an engine.

Another object ofthe invention is to coni struct the valve. with anannular passage v through which the combustible mixturemay operatetofiiood the cylinders ,with oil. 4

Another feature of the invention is lthe means `provided for `drainingback all' surplus'oil to the crank-case. l

With the foregoing and othery objects in view, which will appear as thedescription proceeds, the Vinvention resides," in) the combination andiarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood Vparting from the spirit 0fthe invention. f i

that changes maybe made in the precise Specification of Letterslatent.Patented Tunas-V29, .1920;V I Appli-cation filed November 151918.`serpiaiiwo. 262,661." 'i l' embodiment herein disclosed without .,de- "iIn, the accompanying drawingsel- Figure l is a longitudinal horizontalsectional view through the engine and valve I chamber.

`F 2 is an end elevation ofthe/engineshowing the crank shaft connection`foroperating the valve. y

F ig.` Sis a vertical cross-'sectional view `on line 3 3 of'F'ig. l,showing partsinelevation, the valve being positioned as it]` would lappear on thefsuction stroke. I i

Fig. 4 is a similarview with thev valve positioned as on the compressionstroke.

Fig. 5 is a likesectional view with the* valve positioned as when theexplosion'occurs.

" i... Fig. 6 is a fragmentary longitudinalsvertical sectional viewthrough the valve, l'showing the oil duct, oil inlet and discharge pipeconnections, and oil overflow pipe.

Fig. 7 is a diagrammatic-view indicating a single rotation of the valveand lits "chronological order ofv operation.'

Y Referring now to the letters of reference plzltped upon thedrawingsfits cylinders and C, their water jackets.

denotes the crank case of the engine, Il?,

a designates a crank-shaft journaled in the crank-case'. 15, arepistons, and F, are rods connecting the pistons with the crankeshaft.

G, is a longitudinal tapering valvesupported in a valve' chamberG1connected by suitable ports in the valve chamber with the respectivecylinders inclosed by a lwater jacket C1 communicatinglwith the waterjacket C of the cylinders. -1

Intermediate of the' ends of the valve chamber is an intake connectionH,`to which i agcarbureter I may be attached as shown in Fig. 2 of Vthedrawings.`

Extending. longitudinally within thek valve is an exhaust passage jg fortwo`of the engine cylinders, divided by a longitudinallyv extendingcross partition g1,- forming `anexhaust passage gzffOT the Othel"cylin'y `for the deliveryof the exhaust ygases into the chamber G2, fromWhich they are discharged through the opening G3.

g3 are radial ports adapted to successively communicate With thecylinder ports B1, 'through which .theV combustible mixture is deliveredto the cylinder, and kt'heexhaust gases discharged therefrom.

' ga is an annular longitudinal passage in the valve having anintermediate peripheral 4channel-gb forcomlnunication With thecarbureter I, and vvithrlradial ports g?, for the delivery of theVcombustible mixture to` Athe ports B1, leading to the respectivecylinders. t l

vL, ,denotes a non-heat conducting insulation between the Walls of theannular passage g@ through the valve and its centralex- .haust passageg; that the valve may not expand and bind in its chamber through theheat produced by the lexhaust gases passing rotation of `the valve.

therethrough. f:

M, is a longitudinal Well .or ductl extendingthe length Aof the valvehaving one'of its side YWalls 1M? inclined in 4the direction of the-Gr-4 the intermediate Wall G5 (closing the peripheral gas inlet channelgb from the oilduct M) and passes back to the crankcase through thepipeN1. f

P, designates a suitable oil pump actuatedy from the crank-shaft fordelivering oil lto the duct M, Q, denotesan auxiliary overvalve chamber,

4flow pipe for conducting any surplus oil back to the crank-case, thusrelieving any lpressure caused by the action of the pump,

and thereby providing` against the cylinders becoming flooded With oil.

R, is a Worm gear keyed to the valve stern G2, actuated by a suitabledriving connection S, in turn operated by the engine crankshaft. T.,denotes a spring sleeved on the valve stem and bearing against the end-Wall ofthe valve chamber and against the .gear R, to maintain the valvein an intimate contact relationship with the Wall of the U, designatesthe spar-k plugs of the reispective cylinders.

It Will now be understood ,that the rotation of the valve is relativelyslo\v,-asthe several operations of the respective cylinders k.ln-iovvnassuction compression explo- 7 sion and exhaust are served upon each"revolution of the valvei-.the Wear ,of parts is thus materiallydecreased.

The longitudinal oil duct is of suicient prQYded with an inclined Wallon At each end ofthev one side in order that any surplus oil that mayhave entered 'the vradial ports inthe valve can drain back into the `oilductas the valve rotates into juxtaposition with the Wall of the valvechamberfollovving the passage of'said' oil duct.l f

. By providing the valve With inlet and exhaust passages adapted tocontrol the delivery of the combustible mixture and the discharge ofit's burnt gases through the same .ports of the respective cylinders,'the cost of'manufacture has been reduced and the simplicity ofits'operation has been materially increased. So also by providing-vanon-heat conducting insulation between the inlet Vandthe yexhaustpassages through the valve, the expansionl of the valve and consequentbinding chamber has been overcome. l y Having' thus describedmyinvention, What I claim is:A i Y A 1. The combination With aninternalcombustion engine comprising a plurality of cylinders, a tapering valve,chamber having channels leading to all `of the cylinders, a taperingrotary valve in said valve chamber having an ,annular "longitudinalchannel with ports adapted to i successively register with thechannelsleadi'ng to .the respective cylinders for delivery of ,anexplosive mixture thereto, the tapering valvejbeng Vprovided vvith atapering central longitudinal passage having aA division plateVextending for a portion of its length to form compartments in saidtcentral passage', radial ports in both .compartments of said centralpassage adapted to be brought into registration of the same in.' the`Vvalve with the channels `connected with the .cylinders for dischargeof the burnt gases therefrom, and means actuated by the crank- ,shaftvofthe ,engine for rotating said valve.

In testimony whereof, `I sign this specification in the presence of twoWitnesses.
